Quasi-two-body decays $B_{(s)}\to P{D}_0^{\ast }(2400)\to PD\pi$ in the perturbative QCD approach

Bo-Yan Cui, Ying-Ying Fan, Fu-Hu Liu +1

We study the quasi-two-body decays $B\to P{D}_0^{\ast }(2400)\to PD\pi$ with $P=(\pi ,K,\eta ,{\eta }^{\prime })$ in the perturbative QCD factorization approach. The predicted branching fractio…
